#3. Ghost racers. Think: Super Mario Kart time-trials, except you’re running against a ghost version of your best time on the map. I know the Garmin already does this, but make it social… show me the best times of my friends or other local users.

Dodgeball founders leave Google and that leaves Dodgeball probably dead. Then why did Google buy Dodgeball exactly? Not for the founders…they left. Not for the tech. To build it up into a profitable company? (Nope, they didn’t put any resources into it.) To kill it before some other company (Yahoo, Microsoft) got their mitts on it? For the PR value? Why did they even bother?

Update:Official thumbs-down announcement here. “It’s no real secret that Google wasn’t supporting dodgeball the way we expected. The whole experience was incredibly frustrating for us - especially as we couldn’t convince them that dodgeball was worth engineering resources, leaving us to watch as other startups got to innovate in the mobile + social space. And while it was a tough decision (and really disappointing) to walk away from dodgeball, I’m actually looking forward to getting to work on other projects again.”
